St Michael’s Tower on top of Glastonbury Tor. The current tower was built along with a monastery in the 14th century after the previous church was destroyed by an earthquake in 1275. The earthquake of 1275 was felt from London to Wales,and was reported to have destroyed many houses and churches in England. The adjacent monastery was destroyed during the Dissolution of the Monasteries in 1539 with the last Abbot being hung drawn and quartered at the tower along with two of his monks. There is evidence of Dark Age occupation of the site during the 5th to 7th centuries.

Glastonbury Tor is a hill at Glastonbury in the English county of Somerset, topped by the roofless St Michael’s Tower. The conical hill of clay and Blue Lias rises from the Somerset Levels. It was formed when surrounding softer deposits were eroded, leaving the hard cap of sandstone
exposed. The slopes of the hill are terraced, but the method by which
they were formed remains unexplained. Artifacts from human visitation
have been found, dating from the Iron Age to Roman eras. Several buildings were constructed on the summit during the Saxon and early medieval periods; they have been interpreted as an early church and monks’ hermitage. The head of a wheel cross
dating from the 10th or 11th century has been recovered. The original
wooden church was destroyed by an earthquake in 1275, and the stone
Church of St Michael built on the site in the 14th century. Its tower
remains, although it has been restored and partially rebuilt several
times. The Tor is mentioned in Celtic mythology, particularly in myths linked to King Arthur, and has a number of other enduring mythological and spiritual associations. X
